RIBBON-BLOCKING MACHINE.

. SPECIFIGATION forming part of Letters Patent No. 540,649, dated June 11, 1 895.

Application filed November 15, 1894. Serial No. 528,850. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN EASTWOOD, a citizen of the United States,residing in Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Ribbon-BlockingMachines; and I do hereby declare the following to be-a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form apart of. this specification.

The object of this invention is to provide a ribbon blocking machine ofsimple and dura ble construction, easily handled and operated.

The invention consists in the improved ribbon blocking machine, in itsribbon. block clasping device, and in the combination and arrangementsof the various parts thereof, substantially as will be hereinafter morefully described and finally embodied in the claims.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 is a side elevation of my improved blocking machine, certainportions being shown in section. Figs. 2.and 3 are enlarged frontelevations of the ribbon-block-clasping device in closed and openposition,respectively. Fig. 4 is a sectional view on the line a: m ofFig. 2, and Fig. 5 an enlarged sectional view on the line 'y y of Fig.1.

In said drawings or represents a bed plate provided with standards 12 cand c, the top portions of which are preferably enlarged and thus formbearings b, c? and c for the shafts d and 1' respectively.

On the inner end of the shaft d is arranged a disk f having collar g andset screw h, which latter is adapted to engage loosely the annulargroove 6, and thus allow said disk f to freely revolve on the saidshaft. The other end of the shaft or spindle d is pivoted as at d to thelever d the lower arm (1 of which is pivoted as at d to one end of linkd fulcrumed with its other end as at d to the bed plate a (or to abracket thereon as will be manifest). By means of the thumbscrew b theshaft 61 is secured or held in the required position.

To the outer end of shaft "6, (which latter is in a line with the shaftor spindle d) is secured a pinion 7c meshing with the internallyarranged teeth of the hand wheel m, adapted to revolve with its collar non stub shaft 0, adj ustably arranged by means of out p in the elongatedslot q of bracket 0'. A handle 0" is secured on said hand wheel in anyWell known manner. If desired the hand driving mechanism is replaced bya driving pulley 10 and the shaft 4.' can thus be operated by power.

To the inner end of the shaft 41 is firmly secured a disk shaving collar5 which latter is keyed to said shaft. The disk 3 is provided with aseries (preferably three) of radially arranged slots 3 which arepenetrated in a longitudinal direction by pins .9 on each of which isarranged a sliding block 5 controlled by spiral springs. Said slidingblock is pro- .vided at its inner face with a flange or finger s,projecting beyond the inner surface of the disk 8, and at its oppositeface-with a pin 8 resting in the concentrically arranged curved slots iof disk 2%. The latter is provided with a collar t adapted to freelyrevolve (a limited distance) on the collar 8 of disk .9. The disk 8 isalso provided at or near its outer periphery with a pin or handle .9 andthe disk 25- With a pin or handle t the latter being arranged a certaindistance away from the radial line of the pin 8 as clearly shown in Fig.2 ofrthe drawings.

The operation is as follows: By drawing the handles .9 and t of thedisks sand t respectivelytogether (as shown in Fig. 3) the pins 5 of thesliding blocks 19 carrying the projecting fingers s are forced outwardby means of their engaging curved slots 25 and thus the ribbonblockclasping device is fully opened. The ribbon block A is then placedbetween said fingers s and the handles 5 and t are released. The saidfingers s andtheir sliding blocks 3 are thus returned by action of thespiral springs s and the ribbon block clamped firmly between the saidfingers. The

disk f is now brought to bear against the face 7 of the ribbon block-bymeans of the lever d and the winding of the ribbon is performed in theusual well known manner.

I do not intend to limit myself to the pre cise construction shown anddescribed as various alterations can be made without changing the scopeof my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination with the shaft of a ribbon blocking machine, of anouter disk secured to said shaft and provided with a series of radialslots, a disk loosely mounted on said shaft and provided with a seriesof curved slots, sliding locks arranged in said radial slots andprovided on one side with fingers projecting beyond the face of theouter disk, on its other'side with pins engaging the curved slots of theinner disk, a spring in each radial slot controlling its respectiveblock, and means for turning said inner disk on its shaft independent ofthe outer disk, all said parts, substantially as and for the purposesdescribed.

2. A ribbon block clasping device consisting of an outer disk providedwith a series of radial slots, an inner disk provided with a series ofcurved slots and arranged concentrically with said outer disk, a slidingblock in 0 each of said radial slots provided with a finger projectingbeyond the face of said outer disk, said blocks being also provided withpins adapted to engage the curved slots of the inner disk, and aspiral-spring in each slot controlling its respective block and tendingto automatically return the disks to their normal positions,substantially as described.

3. The combination with the shaft of a ribbon blocking machine, of anouter disk sccured to said shaft and provided with a series of radialslots, a disk loosely mounted on said shaft and provided with a seriesof curved slots, a guide pin in each radial slot, sliding blocks looselyarranged on said guide pins, each block being provided on one side witha finger projecting beyond the face of the outer disk and on its otherside with a pin engaging the curved slot of the inner disk, and a spiralspring around each guide pin and controlling its respective block, andmeans for turning said inner disk on its shaft independent of the outerdisk, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this1st day of November, 1894.
